Ingredients for Chicken Tetrazzini

16-ounces fettuccini: Perfectly al dente to cradle that creamy sauce.
Two 10.5-ounce cans of cream of chicken soup: The velvety base for our easy chicken tetrazzini, lending rich flavor.
8 ounces of softened cream cheese: For that irresistibly smooth and creamy texture, make sure it’s soft enough to whisk.
1 cup sour cream: Adds a tangy depth to the creamy sauce.
1 ½ cups chicken broth: Thins the sauce to the perfect consistency.
1 teaspoon Italian seasoning: Just the right blend of herbs to complement the creamy white sauce.
½ teaspoon pepper: A bit of spice enhances the other flavors.
1 rotisserie chicken, shredded: Effortlessly juicy and tender chicken in every bite.
2 cups shredded mozzarella cheese: Melts beautifully for that gooey, cheese-pull effect.
2 cups shredded cheddar cheese: Adds a sharp, tangy contrast to the creamy mushroom sauce.

How to Make Chicken Tetrazzini

Preheat the oven to 375°F. Grease a 9×13-inch baking dish with butter or non-stick cooking spray.
Shred your leftover rotisserie chicken or cut it into bite-sized pieces.
Cook the fettuccine according to the package instructions until al dente. Drain and set aside.
In a large mixing bowl, stir together the cream of chicken soup, sour cream, chicken broth, Italian seasoning, and pepper until well combined.
Add the shredded chicken, half of the mozzarella, half of the cheddar, and the cooked fettuccine to the creamy sauce. Toss everything together until evenly coated.

Pour the mixture into the prepared casserole dish, spreading it evenly. Sprinkle the top with the remaining mozzarella and cheddar cheeses.
Bake for 35 minutes, or until the cheese is melted and golden brown. Cover with aluminum foil if you notice the cheese browning too quickly.
Remove from the oven and let cool for 5 minutes before serving. Enjoy!

Personalizing Your Tetrazzini

Make this recipe your own with some of these ideas:

Swap in leftover turkey for a twist on the classic dish. It’s a great way to repurpose holiday leftovers into a creamy, comforting casserole.
Add vegetables like broccoli florets or peas to sneak in some greens. Not only does it add a bit of color and crunch, but it’s also a simple way to make this dish a bit healthier.
Try different pastas, such as angel hair, spaghetti noodles, or egg noodles. Each has a different texture and might just become your new favorite.
Incorporate a splash of white wine into the creamy sauce for an added depth of flavor that elevates the whole dish. This small addition can make a big impact on the overall taste.
Experiment with cheeses, like swapping some of the mozzarella or cheddar for parmesan cheese or a sprinkle of fresh parsley before serving for a nice, herby brightness.
Add a little heavy cream for an extra-creamy sauce. It makes the sauce even more decadent, perfect for those days when comfort food is exactly what you need.

Storage & Reheating Tips

Got leftovers? Chicken Tetrazzini stores well and tastes just as delicious the next day!

Refrigeration: Let the casserole cool completely, then store it in an airtight container or cover the baking dish tightly with plastic wrap. It will stay fresh in the refrigerator for up to 4 days.
Freezing: For longer storage, freeze individual portions or the entire dish in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before reheating.
Reheating: Warm leftovers in the microwave for 1–2 minutes per serving, or bake in a 350°F oven for 15–20 minutes until heated through. If the pasta looks dry, add a splash of chicken broth or milk before reheating.

Enjoy a quick and easy meal without the extra effort!
